WILLIAM J, BEHLMER, OF BATESVILLE, INDIANA.

WINDOW-SASH MOUNTING.

Application filed August 16, 1926. Serial No. 129,586.

The object of the invention is to provide a means for mounting sash in a w1ndow frame, whereby the sash may be raised and lowered, as in the ordinary way and in connection with counterbalancing weights, or swung open, as in casement windows; and to provide a construction of thls sort which is of extremely simple form and, therefore, susceptible of cheap manufacture and low marketing price.

With this object in view, the invention consists in a construction and combination of parts of which a preferred embodiment,

is illustrated in the accompanying drawings, wherein:

Figure 1 is a front elevational view of a window frame and its sash, showing the lat ter mounted in accordance with the invention.

' Figure 2 is a transverse sectional view, enlarged, on the plane indicated by the line 22 of Figure 1.

' Figure 8 is a vertical sectional view on the plane indicated by the line 3-3 of Figure 1.

Although the invention may, if so desired, be applied to upper sash, such application is generally thought to be unnecessary and, therefore, in the illustrated'embodiment of the invention, the upper sash 10 is shown mounted for up and down sliding movement between the outer intermediate guide strips or beads 11 and 12 and may be controlled in any conventional way as, for example, by counterbalancing weights 13 connected with the sash by cords 14 trained over guide pulleys 15. 1

The lower sash, which may consist of a single sash or, as in the illustrated embodiment, of the two sash 16, is mounted for swinging movement at its side edges, as in the case of casement windows, or for elevating and lowering as in the case of sliding windows. Where the lower sash is but a single unit, it is hinged at one edge only but where it consists of the double unit, each section is hinged at its side edge. Channel members 17 are provided and constitute the sash guides. These channel members are disposed between the intermediate bead 12 and the inner bead 18, both of these beads on the facing edges being undercut, as indicated at 19, to provide guideways for outwardl extending flanges 20 on the side flanges o the channel members. Thus the channel members are slidable upwardly and. downwardly between the beads and, if the conventional form of control 1 for sliding windows is employed, these channel members are operatively connected with counterbalancing weights 21 by means of cords 22 trained over pulleys 23. The inner edges of the channel members at the junction of the'web portion and flanges are coiled, as indicated at 24, for the reception of a pintle 25, these coiled portions 24 being arranged at uniform intervals and in intercurrent relation with corresponding coiled portions 26 through which the pintle 25 passes, these coiled portions 26 being parts of the plate 27 which is secured to the sash 16.

At the junction of the outer flanges of the channel members with the web portions, there are formed. flanged extensions 28 overlapping the sash 16 on the outer face thereof to provide a weather seal, and a bead 29 seated on the upper face of the sill 30 en- PATENT orries.

gages in a recess/on the under edge of the sash frame when the latter is lowered and provides a weather seal at the lower edge of the sash, the. sash being readily disen gaged from the head by the operation of slightly raising them, thus leaving them free to swing inwardly to open position. If desired, the sash, instead of being opened by swinging them on their hinge connectionswith the channel members, may be raised and lowered as in the ordinary way, the channel members sliding up and down in their guides formed in their intermediate and inner beads 12 and 18. i

The invention having been described, what is claimed as new and useful is:

In combination with a window frame having guide beads, a member mounted between said beads and for sliding movement up anddown, and a sash having a hinge connection with said sliding member, the sliding member being of channel form provided with out-turned flanges at the inner edges its es and the guide beads being unintercurrent relation with the coiled por tions of the channel member, and a pintle eX- tendingthrough said coiled portions. 10

In testimony whereof he afiixes his signature.
